Workshop on preparations for ANConf/12 − ASBU methodology SIP/2012/ASBU/Nairobi-WP/24E Aviation System Block Upgrades Module N° B0-86/PIA-3 Improved Access to Optimum Flight Levels through Climb/Descent Procedures using ADS-B Workshop on preparations for ANConf/12 − ASBU methodology (Nairobi, 13-17 August 2012)

ICAO SIP 2012- ASBU WORKSHOP Module N° B0-86 Improved Access to Optimum Flight Levels through Climb/Descent Procedures using ADS-B Summary This ITP module enables an aircraft to reach a more satisfactory flight level for flight efficiency or to avoid turbulence for safety. Main Performance Impact KPA-02 Capacity, KPA -04 Efficiency and KPA-05 Environment. Operating Environment/Phases of Flight En-Route Applicability Considerations This can be applied to routes in procedural airspaces, Global Concept Component(s) CM, AUO, AOM Global Plan Initiatives (GPI) GPI-9, GPI-7 Pre-Requisites NIL Global Readiness Checklist Status (ready now or estimated date). Standards Readiness √ Avionics Availability Infrastructure Availability Ground Automation Availability Procedures Available Operations Approvals ICAO SIP 2012- ASBU WORKSHOP

ICAO SIP 2012- ASBU WORKSHOP Module N° B0-86 - Baseline ITP using ADS-B is in operational use and hence can be considered to be a baseline. ICAO SIP 2012- ASBU WORKSHOP

Module N° B0-86 – Change Brought by the Module The introduction of ITP and ADS-B based separation minima enable aircraft to climb or descend through the altitude of other aircraft when the requirements for procedural separation cannot be met ICAO SIP 2012- ASBU WORKSHOP

Module N° B0-86 – Intended Performance Operational Improvement Capacity Improvement in capacity on a given air route Efficiency Increased efficiency on oceanic and potentially continental en-route. Environment Reduced emissions Safety A reduction of possible injuries for cabin crew and passengers CBA To be determined ICAO SIP 2012- ASBU WORKSHOP

Module N° B0-86 – Necessary Procedures (Air & Ground) Procedures for ITP using ADS-B have been developed and a PANS-ATM Amendment is in progress. Additional information will be available in an ICAO circular – “Safety Assessment for the development of Separation Minima and Procedures for In-Trail Procedure (ITP) using Automatic Dependant Surveillance – Broadcast (ADS-B) Version 1.5.4” ITP requires the use of CPDLC as per PANS-ATM amendment for an applicability date of Nov 2013. ICAO SIP 2012- ASBU WORKSHOP

Module N° B0-86 – Necessary System Capability Avionics The aircraft performing the in-trail procedure will require an ADS-B IN capability compliant with DO-312/ED-159 or DO-317A/ED-194. The other aircraft involved in the procedure will require an ADS-B OUT capability compliant with AMC 20-24/DO-260A/DO-260B/ED-102A, or DO-317A/ED-194. CPDLC compliant with DO-306 chg 1 / ED-122 chg 1is required. Ground Systems It is recommended that conflict probe logics be adapted to ITP separation minimum. ICAO SIP 2012- ASBU WORKSHOP

Module N° B0-86 – Training and Qualification Requirements The flight crew needs to be trained and qualified to understand the limitations of the equipment and to ensure a correct usage of the In-Trail Procedure and supporting avionics. The controller needs to be trained and qualified to assume the tasks and to ensure a correct usage of the In-Trail Procedure and ground support tools. ICAO SIP 2012- ASBU WORKSHOP

ICAO SIP 2012- ASBU WORKSHOP Module N° B0-86 – Regulatory/standardization needs and Approval Plan (Air and Ground) Regulatory/Standardization Use current published criteria Approval Plans To Be Determined. Operational Approval guidance/criteria may be needed based upon regional application for ATSA. ICAO SIP 2012- ASBU WORKSHOP
